construction which can be manufactured economically.

The`nature of the invention, will be read,-`

. ily understood from the'following descrip-v tion when read 1n connectionwith the accom# panying drawings, and the novelY features will claims.

In the drawings,

Figure l is a side elevation-'of al horse con'- he particularly Vpointed out in the 'appended Struct-ed inl accordance with thisv invention;

2 is a Vperspective'view of theY horse shown in Fig. l, one of the legs, however, he# ing removed; Y i Y Y a Fig. 3 is a perspective view of the adjustable section of -one of the legs; and

Fig. 4 is al vertical,` cross-sectional View showing certaln details of the leg construction.

The construction shown comprises two frame-like sections hinged together at' their upper ends. The right-hand lframe coniprises upright members '2 and 3 connected by horizontal top and bottom v,members 4 and', respectively, allof these members usually heing made of wood. `Another Wooden piece 6 is secured to the part 4. The leftfha-nd frame consists of similarparts designated by primed numerals correspondinglto those used to designate'like parts in the right-hand framesection. Each of these frames is very stiff and rigid, and the two frames are secured to'- getherat their upper ends by two pairs of eyebolts Y, fig. 1, the individuals of each pair being interlocked with each other so that 5 they hinge the two frames together. vVhen the horse/'iis in use the two frame-like sections are spread apart attheir lower ends, as shown i-n F ig. 2, and they rest onthe floor or some similar support. `|'llie floor may be uneven, and dueto the fact that there are four points of contact with the floor, two on each frame, rigid horse would wabble or tip unless the floor or surface on which it rests were in a true plane.V This, of course, rarely happens. However, the loose pivotal connection between the upper ends of the frames permits sni'licient vrelative movement of the frames to allow each frame to find a firm bearing so that any wabhling or tipping of thehorse under the conditions ordinarily met'is avoided.

In order to hold the horse in its operative position vit is equipped with a toggle'mecha- `nism which, as shown,l consists of a loopshaped or vbale-like member comprising'a handle portion 8 and two legs'9f-9, VThese legs are pivoted to the lower horizontal .piece 5 of one frame. The other member `of this toggle consists of a linl; l0 which'is 'pivoted at one' end to the horizontal pieceh of the other frame' and at its opposite end tofthe central portion of the loop-shaped member 8, the

legs of this 'member being bent toward each other` and fastened by a pivot pin 12'to the link. Y

4 This toggle automatically drops into its straightened position when the legs of the horse are spread apart, as shown in Fig. 2,

vvand it positively locks the horse in this position. At the same time: the part 8 forms a convenient handle for lifting the toggle when it is desired to fold or collapse the horse.

A n important feature of this invention resides in the arrangement for adjusting the length of the legs of the horse.y

Referring again to the right-hand frame, it will be `seen that itjincludes two legs, one Consistinr.lr of thevnpper fixedv section 2 and an 4adjustable section a, while the other conpin 13 which projects rigidly therefrom, the

pin having a lateral extension i4 at its ends. Each of the tired leg sectionsalso is provided with a series or holes 15, any one of which is adapted to receive the pin 13. Near its lower end each fixed leg section is provided with a metal guide plate 16 of approximately channel section and comprising a flat portion which is secured firmly to theleg and upright `flanges at opposite edgesthereof betweenv which the part a is received, as clearly shown in the drawings.

In the order to hold the section'a in the guide 16 and to secure the sections of the leg in their overlapping relationship, a clamp17 is provided which consists simply of a metal bar bent into a rectangularorm with the two ends meeting, or nearly so. This clamp is large enough to slide loosely along the leg and embraces both leg sections. It is yieldingly held in its operative position at the lower end vof the leg by a latch 18. The construction or' ,this latch will be readily understood from an inspection of the drawings. It 1s loosely connected to the leg at its upper end by two screws, is pressed outwardly by a coiled spring 19, Fig. 4, and is provided near its lower end with a groove 20 to receive the clamp 17.

Inadjusting the length of the leg 2 the of themember a and this member is then removed and the pin 13 is entered in any desired one of the holes 15. The member a' then is placed in the guide 16 and the clamp 17 is slipped down over both sections 2 and a as far as it will go until it snaps into the groove 2O in the latch 18. 05,6 and of the other legs are then adjusted so that all the'legs are or the same length. The extension 14 on the end of each pin 13 prevents the pin from coming out of the hole, and the clamp 17 on each leg holds the two sections of each leg securely vagainst separation. Since the points at which the clamp 17 and the pin 14 act are relatively remote from each other, and since both act to hold the sections together, any danger of the separation of the sections is avoided, and any possibility of one section slipping on theV other is positively prevented. At the same time the sections can be quiclrlyreleased and adjusted into a different relationship to change the length of the leg.

It will be clear from an inspection of the drawings that any weight placed on the horse will tend to force the fixed leg sections downwardly withreference to the adjustable sections of the legs, and thus will increase the diiculty of withdrawing the pins 13 from the holes 15.

It will now be appreciated that this invention provides ahorse of an unusually sturdy construction, which can be manufactured economically, is very convenient to use, and in which anV ample range of adjustment' for height is provided; Y

-Whil`e I have herein shown and described apiefcrred' f'rmof the` invention; it will be The removable members evident that the invention may be embodiedA ing both sections and slidable on said leg but operative to lock the two sections together, and a latch carried by one of said sections for holding said clamp in its operative position, said latch being operable to release the clamp.

2, A horse of the character described havinganV extensible leg comprising two sections overlapping each other, one section having a pin projecting therefrom with a lateral extension atthe end ofsaid pin'the other sec-y tion having a series of holes each designed to receive said pin, a clamp embracing both sections andslidable on said leg for locking the two sections together, and a Spring actuated f latch for locking said clamp in its operative position but operable to release the clamp. clamp'17 is slipped up above the upperend ,l

3. A horse of the character described having an extensible leg comprising two sections overlapping each other, one section having a pin projecting therefrom with a lateral extension at the end of said pin, the second section having a series of holes each designed Ato receive said pin, a clamp loosely mounted lateral extension at the end of said pin, the

fixed section having a series of holes therethrough each designed to receive said pin, a guide member'rigid with said ixedl section and partly embracing said second section, a clamp slidable on said leg and embracing both sections adjacent to said guide member and serving to lock said sections together, and a latch for'holding said clamp in its operative position, said latch being movable to release said clamp.

5. A horse of the character described comprising two frames" hinged together at their upper ends to swing 'toward and from each other, and a toggle connecting the lower portions o said frames and including a loop shaped member having legs bent toward each other -at an intermediate point in the member, the ends of said legs'bein'g pivoted to one of frameset@ a lnkpveted atonejend to the other frame and at its opposite end to said legs at said intermediate point, a part of said loop shaped member forming a handle for collapsing the toggle.

6. A horse of the character described comprising two rigid ramelike sections forming the opposite sides of the horse and each provided with two legs, the ends of which are adapted t0 rest on the floor, each of said sections including an upper cross member 4 rigid with the two legs of its respective section, and hinge means connecting said cross members of the two sections together and permitting the sections to swing toward and from each other, said means consisting ot hinge members rigid with their respective sections but loosely joined together, whereby they permit a substantial but limited relative movement of the rigid frame sections transversely of the plane of said swinging movement and permit the ends of the legs of each section to find a bearing independently of the other section.
